Abstract:
Power amplifier bias circuit. A power amplifier bias circuit can include an emitter follower device and an emitter follower mirror device coupled to form a mirror configuration. The emitter follower device can be configured to provide a bias signal for a power amplifier at an output port. The power amplifier bias circuit can include a reference device configured to mirror an amplifying device of the power amplifier. The emitter follower mirror device can be configured to provide a mirror bias signal to the reference device.
